The Windsor® XL designer shingle elevates the look of your roof with a higher profile, creating an enhanced dimensional texture for a more pronounced design. Windsor® XL is engineered with the fortified durability of Flexor™ polymer modified asphalt technology to promote superior granule adhesion and extreme weather protection, including Class 4 impact resistance.

Both products feature a Scotchgard™ Protector from 3M for added protection against black streaks caused by algae.

-FLEXOR™ POLYMER MODIFIED ASPHALT-

Raw asphalt must be altered for use in roofing materials. For over 30 years, Malarkey has been mixing a specially formulated blend of polymers with raw asphalt to produce our resilient Flexor™ polymer modified asphalt. This process retains more of the rubberlike characteristics of raw asphalt while adding the enhanced characteristics of polymers, resulting in improved flexibility, granule adhesion, cold weather installation, and impact resistance.
